Creates a handle that watches node probability during propagation.
| Parameters: | nodes (array of ints) – the nodes to watch (e.g. [0,1,4]). |
|---|---|
| Returns: | : creates a handle that can be accessed to retrieve node probabilities for various \(t\) |
| Return type: | pyCTQW.MPI.ctqw.nodeHandle() |
Example
>>> walk.watch([0,1,2,3,4])
>>> walk.propagate(5.,method='chebyshev')
>>> timeArray, probArray = walk.handle.getLocalNodes()
Warning
Note that walk.handle attributes are not collective; if running on multiple nodes, only local values will be returned.
